Transitioning to circular sanitation systems requires not only technical innovation but also viable economic frameworks that can sustain and scale these solutions beyond the project lifecycle. Within P2GreeN, circular business models are developed and tested across the project’s pilot sites, demonstrating how nutrient and water recovery can generate tangible value for municipalities, utilities, and the agri-food sector.

The materials below present the business models elaborated under the project, offering replicable frameworks for stakeholders seeking to implement circular sanitation at local and regional level.
